Said second uprightpipe 34 is short of the floor 13 at its lower end and short of theceiling 12 at the upper end thereof, a damper 36 beingfitte'd near theupper end of said pipe above its junction with said horizontal pipe 35.In

this connection it imay be stated that this horizontal pipe 35 ispreferably connected with a stack (not shown) to augment theu'p draft inthe upright pipe 34. Legs 37 for said pipe 34 support the same fromthefloor fitting in the casing 14allows the upright pipe 34 toclear thehorizontal pipe 19 at one side thereof. To suitdiiferent buildingstructuresand to meet various conditions, such,

for example, as the clearing of a doorway in a wall of a structure, itis advantageous tobe able-to shift the upright pipe 34 to either side aof the horizontal pipe 19. To this end, I pro- 'vide a secondoutletfitting 32 for the down flue C, the same issuing from the casing 14 inangular relationwith respect to said first fit ting 32. One or theotherof said fittings 32v and 32 is selected for connection. with the fitting33 on the upright pipe 34, the unused fitting being sealed by aremovablecap 38.

Normally, 51in heating, ventilating and 'liumidif ing the air in:chamber A, water is,

Ia'dmitte to the receptacle B, past a cut-oil valve 39ftherein,andthrough; the float controlled valve 23. The burners 18 are lighted,

the'dan per 36 closed and the damper 29 therethrough.

' ated air is removed from the lower opened; v Under such conditions,"vapor forming at the receptacle B is picked up in pipe19 Y by freshincoming air impelled upwardly through the heated pipe'20 into thechamber A. Descendin in the chamber as it becomes cooled, theair Followsalong the floor 13 to the lower end of pipe 34 into which it is drawnand from which it passes through pipe The down flue C anditsrelationship with the pipe 20 play an important part inthe efiicient andeconomical operation of the device. That is to say, the rising heatedair and gases from' the burners 18 have a return sweep through said flueand along the pipe 20, thus effectively heating said pipe and therebystrengthening the up draft therein and enlarging its capacity to heatthe incoming air-passing Further, by conducting the heated air and gasesfrom the down flue G into the pipe 34 at a point remotely beneath theupper end of said pipe,a strengthened up draft is produced in that pipe.From the lt will be'noted that the location of the water feed line 22may be closed to discontinue the supply of vapor to the incoming airand, if such adjustment of said valve 39 will not sufli ce,the damper 36may be opened more or less so that the air of highest percentage ofhumidity at the ceiling of the chamber may pass therefrom into pipe 34and thence through pipe 35 to the outer air. I

For simple heating of the chamber, without ventilation, the damper. 29in pipe 19 is closedand cap 28-removed from said pipe 19. The air, thentrapped in the chamber, oir culatcs from the'lower portion of saidchamber to the upper portion thereof and back, the upward flow takingplace in the heated pipes 19 and 20. "And, of course, moisture may beadded to the air moving through said pipes by admitting water to thereceptacle B. j
